BMW stakeholders monitor the water quality in Barr Lake and Milton Reservoir and uploads the data to the Data Sharing Network (DSN). Click here to access the DSN's interactive map. BMW members also collect water quality data about other areas of the watershed. Most of this data is available on the DSN.
